Description of the invention (1) < Please read the precautions on the back before writing this page) The present invention relates to a winding body with a shifting cable and a shift lever for rotating the winding body And can be installed on the bicycle shifting operation device on the handle of the bicycle. The conventional bicycle gear shifting operating device has a structure disclosed in, for example, Japanese Patent Publication No. 48-33173, which is provided with an arrow as a pointer on a circular plate forming a winding body for a shift cable. It will rotate to indicate the speed display mark, so as to display the speed range due to the speed change operation. In the conventional speed display, the pointer is attached to the winding body and moves together with the winding body. Therefore, for example, when the overall device is designed as a small product, the outer diameter of the winding body needs to be reduced. The winding body needs to rotate from the lowest speed to the highest speed. The pointer also moves only a short stroke, and the speed display mark is easy to occur. The interval must be matched with the problem of narrowing. In addition, sometimes due to the operation structure of the speed change device, it is necessary to make the rotation angle of the winding body non-uniform * For example, when the speed changes from 1st speed to 2nd speed, the rotation angle of the winding body and 2nd speed become 3 When the rotation angle of the winding body at different speeds is different, the rotation angular distance of the pointer is also uneven and the rotation angular distance of the winding ceremony is uneven, which causes the problem of uneven spacing of the speed display marks on the movement path of the pointer. The purpose of the present invention printed by the Employee Consumer Cooperative of the Chongyang Bureau of Standards of the Ministry of Economics is to provide a bicycle with a simple structure that can indicate the speed without any restrictions on the size of the winding body or the rotation angular distance, and has a simple structure. Operating device. In order to achieve the above object, the bicycle shift operating device of the present invention is provided with a winding body for a shift cable and a shift lever for rotationally operating the winding body, and can be mounted on a handle of a bicycle, which is characterized by: Winding-3 — This paper scale is applicable to the Chinese National Standard (CNS) A 4 specifications (210 X 297 mm) 81.10.20,000 A6 B6 Central Government Bureau of Economic Affairs Employee consumption cooperation du printing 5. Invention description (2) Viewed in the direction of the rotation axis, the movable element used to display the shift stage is swingably arranged on the axis located on the side of the winding axis of the winding body, and the shift stage indicator of the movable element is arranged on the axis On the opposite side, the transmission protrusion that rotates integrally with one of the above-mentioned winding body or the movable element is interlocked with the linking mechanism of the other by sliding freely to link the winding body with the movable element. During the shifting operation, the rotating force of the winding body is transmitted to the movable element through the transmission protrusion, so that the movable element is rotated from the previous display position to the new display position when the gear shifting operation is not performed, so that the shift stage display portion of the movable element instructs the shift The new gear stage after operation. In terms of the configuration of the interlocking mechanism, for example, a transmission protrusion may be provided on the winding body, and at the same time, it may be slidably locked between the rotation axis of the movable element and the shift position display portion. In this way, the distance from the rotation axis of the movable element to the shift section display portion is greater than the distance from the rotation axis to the input portion, so that when the movable element swings due to the transmission from the winding body, the shift section display portion of the movable element moves The distance is larger than the specific part where the winding body is provided with the transmission protrusion. In addition, according to the setting situation of the position where the transmission element is locked between the rotation axis of the movable element and the speed-changing position display part when the movable element is located at a specific shift instruction position, or the shape setting condition of the sliding locking path of the transmission protrusion, When the winding body rotates at an uneven rotation angle distance, the movable element can also rotate at a uniform or substantially uniform rotation angle distance, and when the winding body rotates at a uniform rotation angle distance, the movable element can rotate unevenly Angular rotation. Also, the speed-changing position display unit can adjust the pitch and then operate, so that the operating distance is enlarged to be greater than the winding body's operating distance, and when the speed-changing stage display unit operates, the rotating angular distance of the winding body is not uniform, The operation pitch of the speed change position display part is also uniform or almost uniform, and the rotation angle of the winding body is 4-1 (please read the precautions on the back before writing this page) The paper scale is in accordance with the Chinese National Standard (CNS) A4 specifications (210 X 297 mm) A6 B6 Printed by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs V. Invention description (3) When the distance is uniform, the action section of the speed change position display section The distance is uneven. Through the movable element, not only can the variable speed section be displayed, but when the movable element operates at a rotation angle or rotation stroke that is not restricted by the specifications of the winding body, the variable speed section display can also be displayed in an appropriate display form that is easy to understand, so that Easily shift to the desired speed range. Moreover, since the transmission protrusion rotates integrally with one of the winding body or the movable element, and at the same time uses a linkage mechanism slidably locked to the other, the linkage mechanism can simplify the structure and reduce costs.
